What is in GungHo Energy Shots?

0

The website is very dense and all about Ninja's and the "proprietary blend" of ingredients. I can't find any actual references to ingredients. It has a "has not been evaluated by the FDA" disclaimer, which basically means it could be anything.

GungHo Energy Shots: This is a dietary supplement, not evaluated by the FDA. When a manufacturer combines ingredients that are already considered "food safe" they can go to market without involving regulatory bodies like the FDA.
Medical Authority: We found a press release and a marketing website with many marketing claims citing an MD (Dr. Perry Renshaw). Dr. Renshaw has impressive credentials. Dr. Renshaw provides alot of commentary without making claims, until he says the following clear assertion:

GungHo will actually increase levels
of critical neurotransmitters in the
brain over time. Thus optimal results
for focus, concentration and brain
health will be seen with the suggested
daily intake.

From what we can see (without further study), this product contains Cytidinediphosphocholine (CDP-choline) or Citicoline. Citicholine is widely available as a supplement in the US, and is prescribed for stroke victims and some other patients around the world.

WebMD notes there are side effects for Citicholine, and that the "safety of long-term use is not known". It was developed in Japan:

Citicoline was originally developed in
Japan for stroke. It was later
introduced as a prescription drug in
many European countries. In these
countries it is now frequently
prescribed for thinking problems
related to circulation problems in the
brain. In the US, citicoline is
marketed as a dietary
supplement...Citicoline seems to
increase a brain chemical called
phosphatidylcholine. This brain
chemical is important for brain
function. Citicoline might also
decrease brain tissue damage when the
brain is injured.

Another study suggested that
citicoline promotes the activity of
phosphocoline cytidylyl transferase
(CTP), the rate-limiting enzyme in the
phosphatid lcholine synthesis pathway
in brain cells.

A study conducted at the Department of
Neurological Surgery, Cardiovascular
Research Center, University of
Wisconsin, reported that citicoline
attenuates phospholipase A2 (PLA2),
which helps to maintain healthy
arachidonic acid metabolism.

As a result, researchers suggested
that citicoline may help to moderate
the formation of reactive oxygen
species, lipid peroxides, and
leukotrienes within cerebral tissue.
